Smarts IP: Card Status UNKNOWN; Card status not monitored.

Products

• VMware

Issue/Introduction

Symptoms:


For a device discovered in Smarts IP, Card Status is displayed as Unknown.

User does not know the status of cards on the device and will not get notified if one of the cards goes down.

Environment

VMware Smart Assurance - SMARTS

Cause

The Card-Fault instrumentation is not included in the devices certification.

Resolution

The discovery of the Card Status on devices is controlled by its certification in the file <IP>/smarts/conf/discovery/oid2type_VENDOR.conf or oid2type.conf. In this file, if the instrumentation section of the certification does not include a line for Card-Fault, you are likely to have issues with the Card Status on the device. This file will need to be modified, using sm_edit as follows:

For OldCiscoChassis:-

In general it is the line Card-Fault= OldCiscoChassis which will need to be added to the certification. 

# Cisco XXXX
.1.3.6.1.4.1.9.1.XXX {
    TYPE = Router
    VENDOR = Cisco
    MODEL = XXXX
    CERTIFICATION = CERTIFIED
    CONT = Cisco-Router
    NEIGHBOR = Cisco-Cdp
    HEALTH = Cisco-Router

INSTRUMENTATION:
    Environment                         = CiscoEnvMon:DeviceID
    CPU/Memory                          = CiscoRouter:DeviceID
    Card-Fault                          = OldCiscoChassis
    Interface-Fault                     = MIB2
    Interface-Performance               = CiscoRouter
    Interface-Ethernet-Performance      = CiscoRouter_Ethernet
}

For Cisco-EntityFRU:-

In general it is the line Card-Fault = CiscoEntityFRU which will need to be added to the certification. 

# Cisco XXXX
.1.3.6.1.4.1.9.1.XXX {
    TYPE = Router
    VENDOR = Cisco
    MODEL = XXXX
    CERTIFICATION = CERTIFIED
    CONT = Cisco-Entity
    NEIGHBOR = Cisco-Cdp
    HEALTH = Cisco-Router

INSTRUMENTATION:
    Card-Fault                      = CiscoEntityFRU
    Environment                     = CiscoEnvMon:DeviceID
    CPU/Memory                      = CiscoRouter:DeviceID
    Interface-Fault                 = MIB2
    Interface-Performance           = CiscoRouter
    Interface-Ethernet-Performance  = CiscoRouter_Ethernet
}

After the relevant change has been made, the certifications can be reloaded without restarting the IP domain using the following command :-

sm_tpmgr -s <AM_Domain> --reloadoid

Check the server log file for any errors. Then delete and rediscover the affected device.      

Additional Information

The OldCiscoChassis MIB is said to be deprecated after IOS 12.1

The Cisco-EntityFRU MIB should replace the OldCiscoChasis MIB however it is apparent from many of the Cisco devices running on IOS versions after 12.1 that the Cisco-EntityFRU MIB  is not available and the OldCiscoChassis MIB is still being utilized. The MIB being utilized for a particular device can be verified by greping for the following OID's in .SNAP file of the device in question:-

OldCiscoChassis          cardOperStatus          1.3.6.1.4.1.9.3.6.11.1.9
CiscoEntityFRUControl    cefcModuleOperStatus    1.3.6.1.4.1.9.9.117.1.2.1.1.2
